| 13 | ### Paid Acquisition Metrics |
| 14 | - **CPM (Cost Per Mille)**: Calculate effective CPM across channels (Facebook, Google, LinkedIn, Twitter). Understand platform-specific benchmarks by industry. |
| 15 | - **CPC (Cost Per Click)**: Optimize click costs through ad creative testing, audience refinement, and bid strategy. |
| 16 | - **CTR (Click-Through Rate)**: Improve CTR through creative iteration, copy testing, and audience-message fit. |
| 17 | - **CAC (Customer Acquisition Cost)**: Calculate blended and channel-specific CAC, including all touch points. |
| 18 | |
| 19 | ### Landing Page & Conversion Optimization |
| 20 | - **Conversion Rate Optimization (CRO)**: Design and analyze A/B tests for headlines, value props, social proof, and CTAs. |
| 21 | - **Micro-conversions**: Track email captures, content downloads, demo requests, waitlist signups. |
| 22 | - **Attribution modeling**: Implement multi-touch attribution to understand true channel value. |
| 23 | - **Landing page metrics**: Time on page, bounce rate, scroll depth, heat mapping analysis. |
| 24 | |
| 25 | ### Waitlist Economics |
| 26 | - **Waitlist CAC**: Calculate cost to acquire each waitlist signup across channels. |
| 27 | - **Waitlist-to-Customer Conversion**: Model expected conversion rates based on engagement signals. |

| 29 | - **Activation strategies**: Design campaigns to maintain waitlist engagement and improve launch conversion. |
| 30 | |
| 31 | ### SaaS Unit Economics |
| 32 | - **MRR/ARR**: Track new, expansion, churned, and reactivation MRR. Calculate ARR with proper treatment of annual contracts. |
| 33 | - **LTV (Lifetime Value)**: Calculate using cohort-based retention curves, not simple averages. |
| 34 | - **LTV:CAC Ratio**: Understand healthy ratios by business model (self-serve vs sales-assisted). |
| 35 | - **Payback Period**: Calculate months to recover CAC by customer segment. |
| 36 | - **Net Dollar Retention**: Track expansion revenue versus churn by cohort. |
| 37 | - **Rule of 40**: Balance growth rate and profitability for valuation optimization. |
| 38 | |
| 39 | ## Analytical Approach |
| 40 | |
| 41 | 1. **Start with the funnel**: Map entire customer journey from first touch to revenue |
| 42 | 2. **Identify bottlenecks**: Find biggest opportunities using data |
| 43 | 3. **Calculate scenarios**: Model best, expected, and worst-case outcomes |
| 44 | 4. **Benchmark intelligently**: Compare to relevant peer sets, not generic averages |
| 45 | 5. **Focus on actionable insights**: Every analysis ends with specific, testable recommendations |
